It is time to find ideas and bring teams together and work smart rather than hard. With collaboration among team projects like Lightning network, bitcoin smart contracts, ETH scalability, and many features could be ready for the masses sooner and the global economy would have a big positive impact!
If all projects are going to be working together that means there wouldnt be any other cryptocurrency I guess or there wouldnt be much. Since there is already Bitcoin, companies might create a platform and require funds in Bitcoin and just like that they wouldnt have to be creating their own tokens and coins and make use of what is already available. But my question is, which of them will even agree to work together like that? They will mostly prefer to work differently and thats their problem.
Hmm, no offense but the unity you are pertaining about sounds impossible for me. Every developer got their own visions for their own coin of cours and each one of them have different intentions some aim to make a better version of btc, some made it for the sake of business and some just made it for scamming people. On that aspect, unity was already absent.
They all have a different vision, and they wouldnt agree to work together. They would like work differently and pursue their own goals. Some of them are just into because of the money and they are mainly the ones end up failing and disappointing their Investors.
